2012-01-25Add support for const pointer to literal-objc string as format attribute.Jean-Daniel Dupas

2012-01-25Switch the ToolChain types to all store a Driver reference rather thanChandler Carruth
a HostInfo reference. Nothing about the HostInfo was used by any toolchain except digging out the driver from it. This just makes that a lot more direct. The change was accomplished entirely mechanically. It's one step closer to removing the shim full of buggy copy/paste code that is HostInfo. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148945 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-25Remove the TargetTriple object that I added to the Driver recently. ThisChandler Carruth
helped stage the refactoring of things a bit, but really isn't the right place for it. The driver may be responsible for compilations with many different targets. In those cases, having a target triple in the driver is actively misleading because for many of those compilations that is not actually the triple being targeted. This moves the last remaining users of the Driver's target triple to instead use the ToolChain's target triple. The toolchain has a single, concrete target it operates over, making this a more stable and natural home for it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148942 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-25Have FreeBSD use even more of the same smarts as Linux is now using forChandler Carruth
adding search paths. Add them only when they exist, and prefix the paths with the sysroot. This will allow targeting a FreeBSD sysroot on a non-FreeBSD host machine, and perhaps more importantly should allow testing the FreeBSD driver's behavior similarly to the Linux tests with a fake tree of files in the regression test suite. I don't have FreeBSD systems handy to build up the list of files that should be used here, but this is the basic functionality and I'm hoping Roman or someone from the community can contribute the actual test cases. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148940 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-25Switch FreeBSD to just include both '/usr/lib32' and '/usr/lib' in theChandler Carruth
search paths for 32-bit targets. This avoids having to detect which is expected for the target system, and the linker should DTRT, and take the 32-bit libraries from the first one when applicable. Thanks to Roman Divacky for sanity checking this. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148939 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-25Switch the Linux C++ standard library header search logic over to useChandler Carruth

2012-01-25Make a major refactoring to how the GCC installation detection works.Chandler Carruth
The fundamental shift here is to stop making *any* assumptions about the *host* triple. Where these assumptions you ask? Why, they were in one of the two target triples referenced of course. This was the single biggest place where the previously named "host triple" was actually used as such. ;] The reason we were reasoning about the host is in order to detect the use of '-m32' or '-m64' flags to change the target. These flags shift the default target only slightly, which typically means a slight deviation from the host. When using these flags, the GCC installation is under a different triple from the one actually targeted in the compilation, and we used the host triple to find it. Too bad that wasn't even correct. Consider an x86 Linux host which has a PPC64 cross-compiling GCC toolchain installed. This toolchain is also configured for multiarch compiling and can target PPC32 with eth '-m32' flag. When targeting 'powerpc-linux-gnu' or some other PPC32 triple, we have to look for the PPC64 variant of the triple to find the GCC install, and that triple is neither the host nor target. The new logic computes the multiarch's alternate triple from the target triple, and looks under both sides. It also looks more aggressively for the correct subdirectory of the GCC installation, and exposes the subdirectory in a nice programmatic way. This '/32' or '/64' suffix is something we can reuse in many other parts of the toolchain. An important note -- while this likely fixes a large category of cross-compile use cases, that's not my primary goal, and I've not done testing (or added test cases) for scenarios that may now work. If someone else wants to try more interesting PPC cross compiles, I'd love to have reports. But my focus is on factoring away the references to the "host" triple. The refactoring is my goal, and so I'm mostly relying on the existing (pretty good) test coverage we have here. Future patches will leverage this new functionality to factor out more and more of the toolchain's triple manipulation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148935 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-24Fix one of the (larger) FIXMEs where we were misusing the Driver's ideaChandler Carruth
of the target triple to stand in for the "host" triple. Thanks to a great conversation with Richard Smith, I'm now much more confident in how this is proceeding. In all of the places where we currently reason about the "host" architecture or triple, what we really want to reason about in the detected GCC installation architecture or triple, and the ways in which that differs from the target. When we find a GCC installation with a different triple from our target *but capable of targeting our target* through an option such as '-m64', we want to detect *that* case and change the paths within the GCC installation (and libstdc++ installation) to reflect this difference. This patch makes one function do this correctly. Subsequent commits will hoist the logic used here into the GCCInstallation utility, and then reuse it through the rest of the toolchains to fix the remaining places where this is currently happening. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148852 91177308-0d34-0410-b5e6-96231b3b80d8
